What is the abbreviation of Misalliance?

There isn't a commonly recognized abbreviation for "Misalliance." It's a relatively long word, and using an abbreviation for it would likely lead to confusion.

If you're looking for a shorter way to refer to it in a specific context, you could use:

* "MA": This is the abbreviation of "Misalliance" itself, though it's not widely used.

* "The play": If the context is clear, simply referring to it as "The play" would be understood.

* "Shaw's Misalliance": This is particularly useful if you're discussing it in a context where multiple plays are mentioned.

Ultimately, the best option depends on the specific situation and what you're trying to achieve.
